TYPE-WRITING MACHINE.

SPECIFICATION forming part 0f Letters Patent No. 636,156, dated OCtOlOer 31, 1899.

Application filed September 26, 1898. Serial No. 691,871. (No model.)

To all whom, t may concern:

Be it known that LNEWMAN R. MARSH-y ments in Type-Writing Machines,of which the following is a specification.

By means of this invention a type-writing Ymachine can be made of simple or cheap construction and capable of easy or rapid operation; and the invention resides in the features of construction set forth in the following specication and claims and illustrated in the annexed drawingsin which- Figure 1 is a plan view of the machine. Fig. 2 is a sectional side elevation of the machine. Fig. 3 is a section along on, Fig. 2.

The base or foot of the machine is shown at -1, and a carriage 2, carrying platen or paper roller 3, can be suitably fed as the writing progresses. A type-bar 4, Fig. 2, being driven by hammer 5 toward the platen, will, by aid of ink-ribbon 6, produce the required print. The type-bars are mounted on a carrier adapted to move or swing about shaft 7,

and these bars swing back and forthor to-l ward and from shaft 7. This carrier is shown in form of a wheel or segment, the rim portion being shown in two parts or sections 8 and 9, the spokes at 10, and the hub portion at 11. The rim being slotted, as seen at 12, the type-bars 4, swinging or. moving in the slots, are properly guided or steadied by ther -slotted upper and lower rims 8 and 9 or guided by rim 8 and supported by rim 9. The type barsor levers 4 are shown with their arms 14, Fig. 2, slotted or forked to straddle or swing on the rod, or fulcrum 15, carried by lower segment-section 9. The slots 12, with forked arm 14, allow the type-bars to be readily removed or inserted into place. The returning-springs 79, connected or removably hitched to their respective type-bars and to upper carrier-section 8, tend to hold the bars or typeclear. from platen 3. The type-bar may be considered as a lever of the first class, with fulcrum between the lever ends, the type end being at 4 and the lifter contacting end at 14. The bars when printing are held or guided bythe fork or guide 16 on post 17, located at the printing-point.

The stem or shaft 7 is shown fixed or secured to base 1, and the carrier-hub 11, sittingloosely about the stern, has a sleeve or tube 18, Fig. 2, with collar 19 resting on tube or sleeve 20, so that the carrier will not sink below the required level on the rod 7. The sleeve 2O is also rotatable on this rod and can be made to rest on base 1. This sleeve 2O has a rearwardly-extending arm 21 and a forwardly-eXtending arm 22, which latter may be called a locking or holding arm, since, as presently seen, it locks or holds the segment 3 while the required type-bar prints or holds the segment in position for the hammer to actuate a bar. The arm 21 has a pin 23 engaging the fork or slot 24 of arm 25, secured to the segment or hub 11. As the segment rotates the arms 2l and 22 are thus likewise rotated. The segment carries a joint or pivot rod 26 for links 27, located one on each side of and a suitable distance from shaft 7. The links are jointed or connected by pivots 2S to a fork portion 29 of arm 30, having the fingerring or eye 31.A This arm 30 might be called a setting-arm, since when moved or swung by the operator it will rotate the carrier S to bring the required type to the printing-point. The arm 30 could be omitted and the setting of the carrier done by arm 22; but the arm 30 is in convenient reach or accessible to the operator.

Rising from base 1 are posts or blocks 32, Fig. 1, suitably spaced to allow the required movement to armY 22. These blocks carry fulerum or rod 33 for the key-levers 34 35, the arms 34 having finger-buttons 36. The hammer 5 may be considered as one arm of a lever, the other arm of which is in form of a bail having arms 37 and cross-piece 38, the fulcrum being at 39. The ring 31 being set over a certain button 36, the carrier 8 is turned to bring the corresponding typebar to the printing-point, and such button 36 being then depressed the corresponding key is actuated, so that arm 35 swings bail 38 to cause the hammer 5 to strike the required type-bar.

On base 1 are suitably-spaced blocks or risers 4l, carrying a guide 40, made in form of a comb or slotted plate. The key-arms 34 when at rest lie in the respective slots in guide IOO 40. The locking-arm 22 is shown provided at its forward part with a fork or lock piece 42, having slot 43. Vhen the setting-arm 30 has been moved to a certain key,the arm 22 has moved slot 43 to such key, so that on the latter being actuated its arm 34 clears or passes out of guide 40 and into slot 43, so as to lock arm 22, with the carrier 8, in position for the required type to print. In other words, the keys or arms 34 are normally raised, so as to lie up in the slots in comb or guide 40. When, however, a button 36,witl1 arm 34, is depressed, suc-h arm 34 swings down away from and out of comb 40 and toward and into the fork 43 of arm 22. The arm 22 is thus locked against motion in either direction by a key-arm 34, entering between the tines or prongs of fork 43.

From the hammerlever 5 37 extends an arm or tail 44, Fig. 2, engaging arm 45 of le- Ver 45 46, fulcrumed at 47. The arm 46 engages the ribbon guide or plate 4S, which is shown having a pin-and-slot connection with the fixed post 17. This guide 4S, with its ribbon, is normally down to clear the view to the platen; but when hammer 5 swings back to print the lever 45 46 is swung to raise the carrier48, with the corresponding ink-ribbon portion, to the printing line or. position. The arm 46 or lever 45 46 when made of springy metal or material can give when required to prevent breakage. The upper part of the ribbon-guide is of course suitably slotted or shaped to allow the type-bar 4 to pass to or strike the platen 3.

The ink-ribbon 6 is shown in form of an endless tape and passes from the ribbonguide 4S to the spools 49, 50, and 51. The spools 49 and 50 are shown with their spindles 52 and 53 rising from base l. To keep the ribbon taut, the spools 50 may have their spindles 53 somewhat springy and tending to pull the ribbon away from the printing-point; but of course the ribbon must not be held back so taut as to interfere with the type-bar giving a proper printing stroke or driving the ribbon against platen The spool 51 is shown mounted on stem 7 and is rotated to feed the ribbon. The carrier-hub 11, in addition to the downwardly-extended sleeve 18, has the upwardly-extended sleeve 54, with arm 55 engaging disk 56, having pawl or spring tooth 57. The spool 51 has at its lower face a ratchet or teeth 58. The carrier, as seen, moves transversely or is rotated from side to side by handle 30, and the sleeve 54, with arm 55 and pawl 56, oscillates with the carrier. As the pawl-tooth 57 swings one way it glides past the teeth 5S, while its movement in the opposite direction is imparted to the spool 51 and the ink-ribbon.v

The type-bars 4 are normally in such position that their arms 14 lie clear of a lifter or block 59 below the printing point or guide 16. When, however, a oar is actuated by hammer 5, the arm 14 comes to rest on block 59, so as not only to firmly support or steady the bai-4 when printing, but also to give said bar a slight lift or rising motion, whereby the type-bar is moved longitudinally or its type brought to the printing line or level even if the carrier 8 should be somewhat out of level. As motion is eased by making the carrier as light as possible, the latter could not be depended on for accurate leveling or alinement of the type-bars. The tendency of the typebars to drop or swing their arms 14 clear from block 59 will cause an easy or rapid return of the type-bar when released after having been forced by the hammer onto the lifter. In other words, the type-bars strike the lifter when printing and clear the lifter when returning to rest.

The block 59 is supported by or has a seat on post 17. The type-bars can each have one or more type, as required. In the drawings are shown three type on a bar, the upper type or case normally printing. To bring another case to print, the carrier 8 must be raised, and to enable the block 59 to be likewise raised to accompany the case-shift of the typebar such block is movable vertically in its seat GO in post 17. The case-shift can be effected by shift-keys 6l and 62, one arranged to shift to middle case and the other to lower case. These keys are shown on opposite sides of the machine, but could both be located at the same side, and a description of one shiftkey explains the action of the other. The shift-key is fixed to cross-arm 63 of a bail, whose arms 64 are fulcrumed at 65. One arm 64 engages under the carrier or its hub 11 and the other under block 59. As the key 61 or 62 or its button 67, with cross-piece 63, is depressed the arms 64 lift the type-bar carrier and block 59 to the required level. Guides 66 can be made to steady the shift-keys and also to limit the play or depression of each key, as required, to shift the corresponding case into action. The shift-hails 63 pivot at 65, and these bails have the arms 62 rigidly secured thereto, so that the arms 62 likewise pivot at 65, and the forks or split blocks 66 guide the arms 62 in their rise and fall.

The feed of carriage 2 can be effected in any suitable way, as the machine is not limited to a particular kind of feed. In the drawings the carriage is shown with a rack 68, and a pawl 69 extends from arm 70, which is mounted on rock-shaft 7l, and as the latter rocks the pawl, oscillating along rack 68, will alternately glide over and take hold of the same to feed. The rock-shaft 71 has arm 72, engaged by arm 73, extending rearwardly from the hammer-lever or its arm 37. As a key 35 actuates the hammer the arms 73 and '72 turn shaft 71 to move arm 70 and pawl 69 in one direction, and a return-spring can be suitably applied to the pawl to return the latter and feed a step on the release of key 35.

The spacing arrangement for spacing between words can be of any suitable kind. An arm 74, extended from rock-shaft 71, is shown ICO IIOl

esente e engaged by arm of space-key 75 76 with button 77 and fulcrum at 78. As the button 77 is depressed the arms 75 74 move the rockshaft 71 the same as the dip of arms 72 and 73.

As each type-bar Jc-swings or is fulcrumed independently of the others, the stroke of the hammer on one bar will not disturb others, the hammer or its fulcrum being located or fixed at the printing-point, so that the particular bar at such point is engaged by the ham mer. The movable or link connection 27 enables the setting handle or eye 3l to swing or be moved toward or from shaft 7 or back and forth, as required, to reach a certain key or button 36, these key-buttons being conveniently arranged in rows or banks. The slits 12 are practically alined with the key-arms 24E, lying forward of fulcrum 33, said arms 34 and slits 12 being arranged to radiate from a common center or stem 7. By suitably bending the arms 35 back of fulcrum 33 out of line with the arms or forward portions 34 said arms 35 will clear post 7. The springy spindles 53 of spools 50 can be steadied or housed in posts or tubes suitably slotted or open toward printing-point 16 to allow the ribbon to be struck or carried to the paper or platen 3. The pin23, being of suitable length, will remain in engagement with slot 24: even when the latter, with the segment, is lifted or moved away from arm 2l.
